Prosthetic and/or orthotic devices (PODS), control systems for PODS and methods for controlling PODS are provided. As part of the control system, an inference layer collects data regarding a vertical and horizontal displacement of the POD, as well as an angle of the POD with respect to gravity during a gait cycle of a user of the POD. A processor analyzes the data collected to determine a locomotion activity of the user and selects one or more control parameters based on the locomotion activity. The inference layer may be situated between a reactive layer control module and a learning layer control module of the control system architecture.

A damping control method for lower-limb prosthesis, which includes the following steps: Isolate the driving motor of the main transmission structure from the driving voltage; The motor is driven to rotate by the force that results from the locomotion of human's CoM (Center of Mass), and generates alternating induced voltage, when the motor behaves as a generator; Connect the output terminals of the motor with a full-bridge rectification circuit that is made of Schottky diodes to transform the alternating induced voltage to direct-current voltage; Connect the output terminals of the rectification circuit with a controlled switch such as transistors or MOSFETs to form a closed circuit, which will generate induced current from the induced voltage; Control the on-off ratio of the switch with the Pulse-Width-Modulation (PWM) signal to generate controllable motor current, which will result in controllable braking torque under the magnet field of the motor. This invention can be widely applied to prosthesis control.

The invention relates to a method for controlling an orthopaedic joint device of a lower extremity. The joint device has an upper part (2) and a lower part (3) mounted in a hinged manner on the latter. Arranged between the upper part (2) and the lower part (3) is an energy converter (5) by which, during walking, kinetic energy from the relative movement between the lower part (3) and the upper part (2)is converted or stored and supplied again to the joint in order to support the relative movement, wherein kinetic energy within one movement cycle is converted and/or stored and, within the same movement cycle, is supplied again as kinetic energy to the joint device (1) in a controlled manner and staggered in time.
